The key quality point for an optical windows are the material and the polishing quality. Below is the most commun manufacturing steps followed by factories:

Outside of their shape optical windows can be characterized by their material and their spectrum of application (UV, visible, IR).

Optical windows can be found in optical distributors of flat optics manufacturer.  According to the complexity of your specification and material you may need to look for specialist (UV, IR, VISIBLE, SAPPHIRE).

Optical windows may also be used as a substrate for further processing. Optical coatings can make them filters or mirrors and metallic coating to offer electromagnetic shielding properties.  Finally marking can be added on surface to make optical masks.

In a nutshell they are used to avoid external elements (water, air, objects..) to enter the equipment while keeping the optical parameters of a system.

Usually windows width are bigger than their thickness but very thick windows may be used for high pressure applications.

Before the discovery of glass and even until the development of its mass production with the invention of float glass, windows where almost non existant. This changed a lot in the last 3 centuries, and now windows are everywhere from our homes to our cars and mobile phones. Below we will focus more precisely on windows used in Photonics : the optical windows.

Beam expanders are telescopes in which a laser beam is expanded to a larger diameter. This can be useful to illuminate a larger area or to reduce the divergence of the beam.

Both are working with polishing pads and polishing slurry which includes abrasive particules, which evolve along the process from gross to fine.  Polishing is the longer processing step for windows taking from some hours to half a day per batch.

Optical windows can be of many different types, round, rectangular, oval or free form shapes. Note that round optics are usually easier to manufacture and to reach high optical specifications, due to their rotational symmetry.

An optical window if an optical component made of transparent material in a certain wavelength range that is usually used for protection of equipment while having little effect on the beam signal.
